  • Patent number: 5657984
    Abstract: A machine for employing the recoil effect of four rubber cords (F) to propel balls at a target for hitting by a batter or as a game of accuracy. The rubber cords are secured to two support poles (A) inserted into the ground and stabilized by four guide wires (D) staked at the front and rear of each pole. These guide wires are offset to the outside of each pole about two feet. An alignment device (B) consisting of a 4'.times.5' mat with a line drawn up its center is used to properly align the support poles with a target (C). A harness (G) having a hole in the middle about 1" in diameter or a pouch into which a ball is placed is also attached to the four rubber cords. The harness is folded over the ball and drawn by hand to a aiming rod (E) which is staked at the end of the center line of the alignment device away from the target. By adjusting the aiming rod left or right and aligning the calibrations on the harness (H) with those on the aiming rod (I), accuracy in hitting the target can be achieved.
